Endogenous Fluorescent Proteins in the Mucus of an Intertidal Polychaeta: Clues...
Rodrigo, Ana P.; Lopes, Ana; Pereira, Ricardo; Anjo, Sandra I.; Manadas, Bruno; Grosso, Ana R.; Baptista, Pedro V.; Fernandes, Alexandra R.The vast ocean holds many unexplored organisms with unique adaptive features that enable them to thrive in their environment. The secretion of fluorescent proteins is one of them, with reports on the presence of such compounds in marine annelids being scarce. The intertidal Eulalia sp. is an example. The worm secretes copious amounts of mucus, that when purified and concentrated extracts, yield strong fluoresce...
Specific Antiproliferative Properties of Proteinaceous Toxin Secretions from th...
Rodrigo, Ana P.; Mendes, Vera M.; Manadas, Bruno; Grosso, Ana R.; Alves de Matos, António P.; Baptista, Pedro V.; Costa, Pedro M.As Yondelis joins the ranks of approved anti-cancer drugs, the benefit from exploring the oceans' biodiversity becomes clear. From marine toxins, relevant bioproducts can be obtained due to their potential to interfere with specific pathways. We explored the cytotoxicity of toxin-bearing secretions of the polychaete Eulalia onto a battery of normal and cancer human cell lines and discovered that the cocktail of...

A study on the digestive physiology of a marine polychaete (Eulalia viridis) th...
Rodrigo, Ana P.; Costa, Maria H.; Alves de Matos, António Pedro; Carrapiço, Francisco; Costa, Pedro M.As for many invertebrates, the gut of marine polychaete species has key physiological functions. However, studies integrating microanatomical descriptions with physiological processes are scarce. The present investigates histological, histochemical and cytological changes in the alimentary canal during the digestive cycle of the marine annelid Eulalia viridis, a species that combines opportunist scavenging, pre...
An integrative assessment to determine the genotoxic hazard of estuarine sedime...
Costa, Pedro Manuel; Pinto, Miguel; Vicente, Ana M.; Gonçalves, Cátia; Rodrigo, Ana P.; Louro, Henriqueta; Costa, Maria Helena; Caeiro, SandraThe application of the Comet assay in environmental monitoring remains challenging in face of the complexity of environmental stressors,e.g.,when dealing with estuarine sediments,that hampers the drawing of cause-effect relationships. Although the in vitro The application of the Comet assay in environmental monitoring remains challenging in face of the complexity of environmental stressors, e.g., when dealing w...
